I'm new to the forum, but I needed more expert advise on the issues I'm having. I have a 2012 Traverse and the AC has a very slow leak causing the system to slowly loose pressure over a matter of months. I've put dye in the system and used a electronic sniffer and have traced the leak to the high pressure relief valve on the bottom of the compressor. I've checked all the typical culprits - evap core(s), condenser, high pressure lines and fittings, Schrader valves (high and low side ports) and the only one that shows any leak is this relief valve. Here is a pic of what I'm looking at:


Is this valve serviceable on this compressor as I cannot seem to find one for this compressor, but I'm finding it for all other makes and models out there. Any advise is much appreciated.
